IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS PERFORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18221134 titled 'IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS PERFORMING THE SAME
Simplified Explanation
The abstract of the patent application describes an image processing method that involves receiving an image, calculating the luminance component of the image, estimating the illuminance component of the image using the luminance component, calculating a gamma value based on the luminance and illuminance components, and calculating the luminance component with an improved dynamic range using a conversion ratio based on the gamma value.
- The method receives an image and calculates its luminance component.
- It estimates the illuminance component of the image using the luminance component.
- A gamma value is calculated based on the luminance and illuminance components.
- The luminance component is then recalculated with an improved dynamic range using a conversion ratio based on the gamma value.
Potential applications of this technology:
- Image enhancement: The method can be used to improve the dynamic range of images, resulting in enhanced visual quality and details.
- Photography: By improving the dynamic range, the method can help capture more accurate and vibrant images, especially in challenging lighting conditions.
- Video processing: The technology can be applied to video processing to enhance the dynamic range of video footage, improving overall video quality.
Problems solved by this technology:
- Limited dynamic range: The method addresses the issue of limited dynamic range in images by recalculating the luminance component with an improved dynamic range, resulting in better visual representation of both dark and bright areas.
- Loss of details: By estimating the illuminance component and calculating the gamma value, the method helps preserve details in both dark and bright areas of the image, reducing the loss of information.
Benefits of this technology:
- Improved visual quality: The method enhances the dynamic range of images, resulting in improved visual quality, better contrast, and more accurate representation of details.
- Enhanced image capture: By improving the dynamic range, the technology allows for better image capture in challenging lighting conditions, ensuring accurate and vibrant representation of the scene.
- Preservation of details: The method helps preserve details in both dark and bright areas of the image, reducing the loss of information and enhancing the overall image quality.
